# Makefile for the Solaris version of battalion 1.3
# (to produce Mesa + OpenGL + TGS binaries)
#
# 9-July-96
#
# Now possible to build a battalion binary "battalion.tgs" using the
# TGS (Template Graphics Software) implementation of OpenGL for ZX.
#

#--------------- Solaris battalion 1.2 --------------------
#
# Makefile targets to build binaries are "mesa", "ogl" and "tgs".
# The ogl and tgs targets create their object files (but not the binary)
# in subdirectories "opengl" and "tgs" to separate them from Mesa object
# files.
#
# Other targets:
#
# Run "make buildlinks.ogl" ONCE to create the opengl directory and the
# symbolic links in it. This will destroy whatever is in the directory!
# "make buildlinks.tgs" does the same thing for the TGS version.
#
# "make clean" removes Mesa object files, "make clean.ogl" removes
# OpenGL object files and "make clean.tgl" removes TGS object files.
#
# "make clean.bin" removes the Mesa, OpenGL and TGS binaries.
